Photoinduced addition and addition-elimination reactions of perfluoroalkyl iodides to electron-deficient olefins

Photoinduced radical perfluoroalkylation of various simple electron-deficient olefins was achieved in the presence of an aqueous Na2S2O3 solution. The reactions proceeded smoothly to give addition or addition elimination products. The ability of the products to be used as radical precursors or Michael acceptors was also demonstrated.
